Customized OS2 Indoor Multi-Fiber Bunch Cable, LC/SC/FC/ST/LSH, 0.9/2.0mm Breakout

Engineering teams can use the documented values below to compare the product with the intended channel and as-built requirements. This made-to-order multi-fiber cable is a pre-terminated indoor item built exactly to the design the project specifies: connector styles and polish at every end, fiber count, jacket rating, breakout geometry and length are all selected at order time, and the finished trunk is optically tested leg by leg before dispatch. The bunch design arranges the 0.9mm tight-buffered fibers around a central strength member inside a round trunk, giving a flexible, pulling-friendly cable for congested indoor pathways.

Product Highlights

Backbone routes turn through tight tray corners, congested risers and crowded vertical channels. The G.657.A1 bend-insensitive fiber in the supplied assembly tolerates a 10mm fiber bend radius; therefore, a hurried routing decision during a night service work window does not on its own turn into a measurable penalty on the optical path. The glass remains fully compatible with the G.652.D plant it connects to.

A pre-terminated OS2 trunk carries the links that leave the room: riser spans between floors, campus backbones between buildings and each wavelength-multiplexed service in between. The glass is the matching section used in the outside plant; therefore, this manufactured assembly does not on its own become the weak point of the loss-budget calculation. At 1310 and 1550nm the attenuation stays a fraction of a decibel per kilometer, and every factory-polished connector adds less than 0.3dB when the end faces are clean and seated.

The breakout is where a trunk becomes usable. Equal-length legs suit a straight row of adjacent ports; at the same time, staggered legs reach a column of ports without slack piling up at one end. The 2.0mm legs survive patching-field handling; the 0.9mm configuration suits protected routing inside panels and cassettes. Deciding on the geometry at order time means this manufactured assembly arrives matching the hardware it serves.

A pre-terminated trunk is only as good as its journey through the pathway. The optional pulling eye protects the connectorized end during the pull and keeps the relevant trunk from twisting, which matters on long riser runs and congested trays. The deployment load rating on the datasheet is the number the pulling rope ought to respect, not the weight of the reel.

Because a multi-fiber trunk is planned once and fitted once, the planning deserves the hour it takes. Measure the channel through the actual containment, note the bend space at the two connection points, and decide which end gets pulled. State the pulling eye requirement with the order if the channel is long or congested. At the far end, leave the dressing slack the relevant panel or cassette needs - the datasheet breakout lengths are the default, and other geometries are confirmed before production is released.

Terminating OS2 fiber in the field means a splicer, a tray mounting point, consumables and the craft time to do it well - multiplied by each fiber in the relevant trunk. A pre-terminated item moves all of that work to the factory floor, where polishing, inspection and testing happen under controlled conditions. The installer who receives the relevant cable routes it, dresses the legs and mates the connection interfaces; the optical path is ready for light the matching hour. For multi-fiber counts the saving is not equivalent to linear but compounding, given that each field-terminated leg is a different chance for a rework visit.

This design is built with 2 Fibers per trunk, terminated and tested as a full item.

Regular length versions cover the common routes: 1m (3ft), 2m (7ft), 3m (10ft), 5m (16ft), 10m (33ft), 15m (49ft), 20m (66ft), 30m (98ft), 25m (82ft), with made-to-order length offered beyond the list, including foot-based builds for projects specified in imperial units. Specifying the measured channel length keeps the slack out of the tray and the strain off the connection interfaces.

Each trunk is terminated with precision zirconia ferrule connectors and optically tested leg by leg before packing: insertion loss and return loss are verified on every fiber, and end-face geometry is inspected for consistent physical contact. This manufactured assembly ships with dust caps on each relevant connector and the test results offered on specify.

Refer to this design by fiber mode, fiber count, connector pair, breakout geometry and length when requisitioning a quotation. For configurations outside the listed options - mixed connector families, jacket ratings, pulling eye, identification or project packing - send the requirement with the enquiry and the factory will cross-check the build before production is released. Project orders can include documentation and labeling requirements alongside the technical configuration.
